EMERGENCY WHEEL.

Specification of Letters Patent.

Patented Aiig. 6, 1907.

Application filed May 21, 1906. Serial No. 318,080.

To all whom it may conccln;

Be it known that I, GnonGE H. TREADGOLD, a citizen of the United Statesof America, residing at Port Huron, in the county of St. Clair and Stateof Michigan, have invented certain new and useful Improvements inEmergency-Wheels, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to new and useful improvements in wheels andparticularly to an emergency wheel which may be applied to the wheel ofan automobile or other vehicle in case the tire of the permanent wheelis punctured or otherwise deflated, or the wheel itself is injured.

The invention consists in the novel arrangement and combination of partsas will be more fully hereinaiter described and set forth in the claims.

In the drawings, Figure 1 shows a side elevation of an automobile wheelwith a portion of the emergency wheel applied; Fig. 2 is a sideelevation of the assembledemer'gency wheel, and Fig. 3 is a sideelevation of a modified form of emergency wheel. Figs. 4 and 5 arelongitudinal elevations partly in section of wheel hubs with theemergency wheel hubs applied.

A is the ordinary wheel of an automobile, or other vehicle, andcomprises the hub B, the spokes G, and the tire D.

The emergency wheel preferably consists of complementary sections E andE comprising complementary fellysections F and F, spokes G, andcomplementary hub sections H and H. The hub sections are preferablyprovided with oppositely projecting lugs h, and in assembling the wheelthe lugs h on the section H are secured to the lugs h on the section Hby bolts-h.

The felly sections are attached to each other at their meeting ends bymeans of segmental straps or clips f secured thereto by bolts j passingthrough suitable apertures. If desired straps f may be provided for eachside of thesections.

The hub sections are arranged to fit the hub B of the vehicle wheel. Ihave shown the, hub.B as conical and consequently the aperture betweenthe hub sec- ,tions is conical, but it is obvious that said aperture maybe made cylindrical to fit cylindrical hubs 'when desired. To preventmarring the hub B, a collar I of leather or other suitable material ispreferably inserted between said hub and the emergency sections, and maybe integral, as shown, or in two sections.

In Fig. 3 I have showna modified construction in which the outersurfaces oi.the hub sections 3' and J are threaded to engage a suitabletaper nut K. The

whgel sections 0 and O are further connectedby bolts i L passing throughspokes M and M and N and N respectively. v

The wheel sections are preferably provided with suitable metal or solidrubber tires as shown at P and are of a slightly greater radius than theradius of the vehicle wheel when the tire thereof is deflated in order Ithat when the emergency wheelis applied thereto it will take the loadfrom the deflated tire The operation of the device is as follows: When atire of the vehicle wheel is punctured or the wheel or tire is otherwiseinjured, the operator applies one of the sec- .tions to the side of thatportion of the injured wheel which is off the ground and secures itthereto by suitable clips or leather straps R engaging the spokes of thetwo. He then moves the vehicle to rotate the wheel until the sectionrests on the ground and sustains the load as shown in Fig. 1 and thesection thus operates as V ,a jack. The second section is then appliedand secured to the first, and thevehicle is then ready to proceedwithout damage tothe deflated tire.

What I claim as my invention is:

1. The combination with a vehicle wheel, of a wheel of normally greaterdiameter than said vehicle wheel and ar ranged to be detachably securedthereto to take the 1021 therefrom, substantially as described.

2. The combination with a vehicle wheel, of a wheel of normally greaterdiameter than said vehicle wheel and a1 ranged to be detachahly securedto the hub thereof to take the load therefrom, for the purposedescribed.

3. The combination with a vehicle wheel, of a sectional wheel arrangedto be secured to the side of said vehicle wheel to take the loadtherefrpm, for the purpose described.

4. The combination with a vehicle wheel, .of a wheel formed ofcomplementary sections detachably secured to one end of the hub of saidvehicle wheel for the purpose described.

5. The combination with aivehicle wheel, of a wheel section of greaterradius arranged to be secured to the side thereof whereby the vehiclewheel may be rotated to transfer the load to said Wheel section and acomplementary wheel section arranged to be secured, to said firstsection and said vehicle wheeLrfor the purpose described.- 7

6. The combination with a vehicle wheel, of complementary wheelsections, means for securing said sections to each other-near theirperipheries, and means for securing the hub sections to each other andto the hub of said vehicle wheel.

- -7. Thecombination with a vehicle wheel, of complementary wheelsections, means for securing said sections to the spokes of said vehiclewheel, and means for secur ing said sections toeachother and to the hubof said vehicle wheel.

In testimony whereof I affix my signature in presence of two witnesses.-
